Bob Cat ran an experiment where he monitored the intensity of the color of a reactant with a spectrophotometer, and used Beer's Law to convert that intensity to a concentration in molarity. He monitored the experiment for 5 minutes. When the experiment was finished, he calculated the natural log of the concentration at each time, and the reciprocal of the concentration at each time. When he graphed all three forms of the data, the plot of the concentration versus time was a line with a slope of -0.045 M-1. What are the order and the rate constant for this reaction? a. zero, 0.045 M/s.
b. zero, -0.045 M/s.
c. first. 0.045 M/s.
d. first. -0.045 M/s.
e. second0.045 M/s.
f. second -0.045 M/s.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
